14 Claims.

This invention relates to car roofs, particularly car roofs with inside carlines. It has for its principal object to provide a roof of this type with ,means adapted to stiffen and strengthen the roof and also to constitute beams for carrying loadlifting devices. Another object is to provide stirrups that support the load-lifting devices and are slidable on the beams and to provide for their attachment to and removal from the ends of said beams. Other objects are simplicity and cheapness of construction and compactness of design. The invention consists in the arrangements and combination of parts hereinafter described and claimed.

In the accompanying drawings, which form part of this specification and wherein like symbols refer to like parts wherever they occur,

Fig. 1 is a plan view of a portion of a car roof embodying my invention,

Fig. 2 is a vertical transverse section through one-half of the roof on the line 22 in Fig. 1,

Fig. 3 is a vertical longitudinal section through the roof at the ridge on the line 3-3 in Fig. 1,

Fig. 4 is a vertical cross-section on the line 44 in Fig. 3; and

Figs. 5 and 6 are sectional views similar to Fig. 3 illustrating constructions of modified form.

Referring to the accompanying drawings, my invention is shown in connection with a car roof comprising Q-bar side plates 1 that are connected by car-lines 2 of substantially channelshaped cross-section with laterally projecting top flanges 3, which serve as supports for the side marginal portions of roof sheets 4. The Z-bar side plates 1 are preferably arranged with their webs horizontal and with their inner flanges projecting upwardly. The carlines 2 gradually decrease in depth from the ridge toward the eaves where they are provided with depending end flanges 5 that overhang and are riveted to the outer faces of the upstanding inner flanges of the side plates 1.

The roof sheets 4 are provided with downturned eaves flanges 6 that overlap the upstanding inner flanges of the side plates 2 and are riveted thereto. The side margins of the roof sheets are overlapped and rigidly secured together and to one of the outstanding top flanges 3 of the carlines by rows of rivets '7. The roof sheets are also secured to the other lateral top flanges 3 of the carlines by rows of rivets 8.

A running board 9 extends longitudinally of the car at the ridge and is supported on top flanges of Z-shaped running board saddles 10, whose base flanges rest on the roof and are rigidly Pennsylvania 1932, Serial No. 587,196

secured thereto by the rivets 7 that secure the overlapped margins of the roof sheets together Adjacent carlines are connected together, preferably at the ridge, by members that serve as struts to stiffen the roof and as beams for supporting therroof sheets and for carrying loadlifting devices. Each of the beams shown in the accompanying drawings comprises a member or section 11 located above the roof sheets and a member or section 12 located beneath the roof sheets. The upper beam section 11 preferably comprises a relatively narrow inverted channel of gradually increasing depth from its middle to its ends that extends from carline to carline and has outstanding base flanges 11a that rest on top of the roof sheets 4 and are rigidly secured at their ends to the opposing top flanges 3 of said carlines by the rivets 7 and 8 which secure the roof sheets to said carline flanges. The lower beam section 12 preferably comprises a relatively wide channel that has outstanding base flanges 12a and is disposed beneath said roof sheets with its web riveted to the base flanges 11a of the upto be attached to and removed from the ends of said beam section.

In the construction shown in Fig. 3, the lower section of the load-lifting beam is shorter than the distance between the opposing side flanges 3 of adjacent carlines, and has no direct connection at its ends with said carline flanges.

In the construction shown in Fig. 5, the lower section of the load-lifting beam extends beneath and is secured at its top to the undersides of the opposing top flanges 3 of adjacent carlines by the rivets that secure the roof sheets to said flanges; and the base flanges of said lower beam section terminate short of the sides of said carlines to iacilitate the attachment of the stirrups to and their removal from the ends of said beam section. In this construction, the top of the lower beam section is ofiset downwardly intermediate its middle and ends to provide spaces 15 between said section and the roof sheets so as to permit ropes or chains to be thrown over said beam section.

In the construction shown in Fig. 6, the lower section of the load-lifting beam gradually decreases in depth from its middle towards each end, which is closed and rigidly secured flatwise by rivets 14 to the adjacent side wall of the carline. In this construction, the base flanges of the lower beam section terminate short of the ends thereof, thereby permitting the stirrup 13 to be slid on and off the ends of said flanges.

By the arrangements described, adjacent carlines are rigidly connected together by members that serve as ties and struts to prevent the carlines from tilting or bowing. These carline connection members also serve as beams for supporting the sheets between carlines; they also serve to distribute the vertical load applied thereto between adjacent carlines; and they also serve as beams for slidably supporting the, stirrups to which lifting tackle or other devices may be secured, which stirrups may be readily attached to and removed from the lower members of the supporting beams by sliding them on and off the ends of said beams.

What I claim is:

l. A car roof comprising carlines, roof sheets spanning the spaces between carlines and rigidly secured thereto and a beam located between adjacent carlines, said beam comprising upper and lower sections located above and below the roof sheets, respectively, and riveted together, the upper section extending from carline to carline and being rigidly secured thereto, and the lower section having supporting flanges terminating short of said carlines.
